Stimlight 850 nm: infrared head and how to use it
What does 850 nm mean, why is infrared light barely visible, and how should you choose the mode, duration and distance? A practical guide to the Stimlight infrared head.
01 · What 850 nm means
850 nm is a wavelength. The abbreviation nm stands for nanometre. This wavelength is in the near-infrared region, beyond visible red light. It does not specify power, session duration or pulse frequency.
02 · Red and infrared heads
The source material for this article lists the red head at 625 nm and the infrared head at 850 nm. The infrared head supplements the system’s four coloured heads. Check the supplied accessories and compatibility against your model’s instructions. Do not automatically use the red head’s duration for the infrared head. Wavelength alone does not establish suitability for a health condition.
03 · Why you can barely see the light
Near-infrared radiation is not normally visible to the human eye, so the head may appear dim. Visible brightness does not confirm output, correct operation or a fault. Check operation only as instructed in the manual; contact the seller if uncertain. Never look directly into the head.
04 · Understanding the specifications
The same wavelength does not mean the same device or the same result. A rating of 850 nm cannot determine session duration or guarantee a depth of action. Research involving a different device cannot automatically be applied to Stimlight.
- Wavelength · nm
- The spectral region of the light.
- Optical power · mW or W
- Energy emitted per unit of time.
- Irradiance · mW/cm²
- Power reaching a unit of area.
- Time · seconds or minutes
- The duration of use.
- Pulsing · Hz
- The number of pulse repetitions per second.
- Distance and area
- The conditions under which light reaches and covers the surface.
05 · Practical steps for use
These steps are a general guide. If the manual does not specify the time or distance for the infrared head, ask the seller for those instructions before use.
- Read the instructions for your model and infrared head, including all restrictions.
- Check the condition of the device and head. Follow the instructions for changing and connecting the head.
- Prepare your skin and the area of use as directed by the manufacturer.
- Keep the specified position and distance. Select a mode intended for this head. The source material lists 2 Hz, 20 Hz and continuous light; check availability on your model.
- Set the duration specified for the infrared head and selected mode. Do not add together durations for different heads without instructions.
- Switch off after use and clean or store the device as instructed.
06 · Safety and limits of use
Follow all restrictions and eye-protection instructions in the manual. Dim light is no reason to extend a session or move the head closer. If you take medicines that increase light sensitivity, or are unsure because of a health condition, discuss suitability with a doctor. Stop if you experience discomfort or irritation. Do not let use of the device delay assessment of health symptoms.
07 · Frequently asked questions
Why can I barely see any light?
850 nm is in the near-infrared region. Low visibility alone does not indicate a fault; check operation as instructed.
Does 20 Hz mean the same thing as 850 nm?
No. Hz describes pulse repetition, while nm describes wavelength.
Can I use the red head’s session time?
Only if the instructions explicitly allow it for the infrared head and selected mode.
How far should the head be from my skin?
Use the distance in your model’s instructions. There is no universal distance specified here for every version.
Should I feel warmth?
Warmth is not a reliable measure of optical output or appropriate session duration. Stop if the heat feels uncomfortable.
Do I need protective eyewear?
Follow the eye-protection requirements in the instructions. Do not look directly into the head or choose protection based on its apparent brightness.
Should I apply gel or cream?
Only use a product permitted by the instructions. Do not apply instructions for ultrasound or galvanic devices to a light head.
Can I combine the infrared head with other heads?
Follow the manufacturer’s procedure. Do not combine session times or modes without appropriate instructions.
What if I am unsure whether the head works?
Follow the manual’s checking procedure or contact the seller. Do not test it by looking directly into the light source.
Will the head work with an older Stimlight?
Ask the seller to check the exact model and version. A matching name or appearance does not confirm compatibility.
